jsTree Open a branch

Question

I am using the JQuery plugin jsTree, http://www.jstree.com/ I am able to expand the whole tree with the following method:

$(\"#tree\").jstree(\"open_all\");


        

Answer 1

Try this code to open node till nth Level

$("#myTree").jstree({options}).bind('loaded.jstree', function (e, data) {
    /** 
     * Open nodes on load (until x'th level) 
     */
    var depth = 3;
    data.inst.get_container().find('li').each(function (i) {
        if (data.inst.get_path($(this)).length <= depth) {
            data.inst.open_node($(this));
        }
    });
});

Answer 2

Your code for open branch is correct.

For example. Source of tree:

    <div id="treeTask">
       <ul>
          <li id="node_37"><a href="#">TEST1</a>
              <ul>
                  <li id="node_38"><a href="#">TEST2</a></li>
                  <li id="node_39"><a href="#">TEST3</a></li>
              </ul>
          </li>
      </ul>
   </div>

Open node:

$("#treeTask").jstree("open_node", $("#node_38"));

Answer 3

None of previous worked for me, so I have created this code, and it works like a charm :)

$('#tree').on('open_node.jstree', function (event, data) { 
    if(data.node.parent !== "#") { 
        data.instance.open_node(data.node.parent); 
    } 
});

Answer 4

i found Ted's code working, but had to change it a bit:

 $('#jsTree').bind("open_node.jstree", function (event, data) { 
      if((data.inst._get_parent(data.rslt.obj)).length) { 
        data.inst.open_node(data.inst._get_parent(data.rslt.obj), false,true); 
      } 
    });

Answer 5

    // Expand pasted, dragged and dropped node for jstree 3.3.1
        var objtree = $('#jstree');
        objtree.bind('paste.jstree', function(e, d) { objtree.jstree('open_all', '#' + d.parent); });
        $(document).bind('dnd_move.vakata', function(e, d) { objtree.jstree('open_all', $(d.event.target).closest('.jstree-node').attr('id')); });
        $(document).bind('dnd_stop.vakata', function(e, d) { objtree.jstree('open_all', $(d.event.target).closest('.jstree-node').attr('id')); });

Answer 6

You could use the binding

$("#tree").bind("open_node.jstree", function (event, data) { 
  if((data.inst._get_parent(data.rslt.obj)).length) { 
    data.inst._get_parent(data.rslt.obj).open_node(this, false); 
  } 
});
